On Monday, news broke that Aaron Hernandez, who is being held without bail after pleading not guilty to murder in the death of 27-year-old Odin Lloyd, assaulted a fellow inmate at at Bristol County (Mass.) House of Correction and Jail.

The initial report indicated that Hernandez, who was being held in isolation because of his celebrity status, came in contact with the fellow inmate while walking in a hallway. The inmate reportedly had been harassing Hernandez nonstop, which may have been the reason the former New England Patriots tight end lashed out.

But on Wednesday, reports surfaced indicating that the man Hernandez assaulted was in handcuffs at the time of the attack and was therefore unable to defend himself from the 6-1, 245-pound former professional football player.

From TMZ: Our sources tell us ... Aaron was NOT wearing handcuffs when he was allowed to go for an isolated walk in a hallway at Bristol County Jail on Tuesday ... but the other inmate he encountered WAS in 'cuffs.

As we first reported, the other inmate had been talking smack to Hernandez ... and Aaron had been upset. When they got into the hallway, Aaron attacked ... and we're told he beat the crap out of the guy.
